071 FNUS22 KWNS 271904 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0203 PM CDT Thu Mar 27 2025 Valid 281200Z - 291200Z The previous forecast reasoning remains largely valid. Minor changes were made to the Southwest/southern High Plains Elevated area to account for recent guidance. Within the Blue Ridge Vicinity, dry and occasionally breezy conditions are possible. Sustained winds still appear too light for highlights, however. Elsewhere, changes are as follows: ...Central Plains... An Elevated area was added to portions of central Nebraska into southeastern South Dakota. The expectation is for RH to fall to around 20% behind the surface trough where downsloping will occur. Duration will be the main uncertainty, but enough of the region should see Elevated conditions for a few hours tomorrow afternoon. ...Western Florida Peninsula... Wind speeds will be slightly higher than on Thursday while RH will probably be similar. Winds of 10-15 mph over very dry fuels will support an Elevated fire weather threat along the western coast. ..Wendt.. 03/27/2025 .PREV DISCUSSION... /ISSUED 0201 AM CDT Thu Mar 27 2025/ ...Synopsis... As the upper ridge over the central US moves eastward, broad troughing across the West Coast will gradually move over the Southwest and Southern High Plains. Increasing southwesterly flow aloft will allow westerly downslope winds across parts of NM and west TX with dry conditions and some fire-weather risk. ...Southern High Plains... As broad troughing moves into the Southwest, stronger westerly flow aloft will first appear over parts of western NM and gradually spread into west TX. Downslope trajectories and warm temperatures will support critical RH values of 15-20% through the afternoon. Aided by deep mixing, stronger westerly flow, and a lee trough, westerly winds of 15-20 mph appear likely. Given the increase in dry fuels, elevated to locally critical fire weather conditions are expected as the mid-level jet overspreads southern NM/southwest TX during peak heating. ...Central Plains... Dry southerly flow is possible over parts of the central Plains Friday afternoon. While not expected to last long as deeper moisture arrives from the south, afternoon RH values may briefly touch below 30%. With southerly gusts of 20-25 mph and dry fuels, locally elevated fire-weather conditions are possible for a few hours. ...Please see www.spc.noaa.gov/fire for graphic product... $$
